Presence Sensor with Audio Analyzer

Presence Sensing

Using the ultra-wideband sensor, customer presence is measurable in multiple aspects including presence, proximity, and length of time. The sensor can be hidden behind wood, plastic, or glass fixture elements. Its wide angle reception pattern (140^o) and variable range, ensures useful data collection.

Audio

The SR-PA1 has an on-board frequency analyzer. An example application is in an active speaker demonstration. Used in combination with an Access Connected World media player, the frequency analyzer can be used to confirm speaker functionality using a tone test.  As each loudspeaker plays back a test tone generated by the audio player, the SR-PA1 reports the minimum, maximum, and average amplitude values of the tone over a set time period. The ultra sensitive frequency analyzer can even distinguish the test tone from background noise.
